 ![Tips](../../d303-docs/images/tips.png)
-USB interface is designed for power supply and uart for data communication.
-if you connnect this evk to a host-device like computer or SBC device, it will 
-work in uart mode.Now usb interface will power supply rtk module and be as a uart
-interface, but Bluetooth will not work.
+USB interface is designed for power supply only.
 
-<br>
-If you want use it as a Bluetooth rtk receiver, please prepare for a power bank
-or any power-only source to power supply this module.

-#### 1.prepare for software
-

-
-  Please download rtklib, we will use it to perform our evk test.
-
-  As a part of rtklib, strsvr is a powerful stream server utility.
-<br>
-
-
-#### 2.strsvr instance 1
-
-  get data from uart output to tcp server for rtk correction and 3rd part app 
-
-  connect evk to computer via usb port,config serial port parameters.

+#### Power
+1.Connect usb interface to USB adapter or Power bank.
+the Current must be more than 300mA.

-#### 3.strsvr instance 2
+2.the Power LED red light will be on.
 
-  get RTCM data from VRS/Base station via NTRIP client,then feed to tcp server
-  
-  ![](../images/str-4.png)
+#### WiFi connection
+1.The device will create a WiFi AP, the SSID: YRTK-XXXXXX.
+"XXXXXX" is the last 6 digits of MAC address.
 
-#### 4.the 3rd party APP
+2.Connect this WiFi in your phone or Laptop, then open the http://192.168.4.1 in Chrome or Safari.
 
-  get RTK solution from tcp server by NMEA-0183 protocol.

-### Bluetooth mode
+3.Press "Scan" to find your local WiFi or the hotspot created from your Phone.
 
-**We recommend using SW Maps to test the bluetooth mode.**
+![](../images/Y-RTK-2-AP.png)
 
+above "192.168.xx.xx" is your new IP address, please remember it.
 
-![](../images/sw-map-0.png)
+#### NTRIP client information
+1. Please config the NTRIP client account.
+2. if your reference station is VRS, please config NMEA relay back.
 
-SW Maps is a multi-functional GIS data acquisition software from Nepal,which can be used for point, line and polygon data acquisition, and can easily try Google Maps/Image Maps, OSM Maps, etc. 
+#### Android app for test
+[blueGNSS](../files/blueGNSS.apk)
 
-The key is that this software is still licensed for free.
-Our Bluetooth mode operation will be based on this software.
+![](../images/blueGNSS-1.jpeg)
+![](../images/blueGNSS-2.jpeg)
+![](../images/blueGNSS-3.jpeg)
 
-There are several ways to get the software, one is to download and install it from the google play store, and the other is to download it from our built-in appbus, only the second download will not be the latest version.
 
-#### Steps
-
-1. Powering your device from the USB port with your power-bank. You'll see the power indicator light up.  
-
-2. In your android phone, find Bluetooth setting in system settings, then paired this evk. The evk's bluetooth name is like ET10_SPPAAxxxx. The last 4 digits are the last 4 digits of a Bluetooth MAC address

-
-3. Open SW Maps, 
-   - click "Bluetooth GPS"
-   - set "u* RTK" as current device 
-   - fresh device to find you just paried device (like ET10_SPPAAxxxx) 
-   - "connect"

-4. re-click left side bar,you will fina a new menu "NTRIP connection" after rtk receiver connected.
